In the world of TV being on a show that goes longer than one season is often a surprise and a wonderful way to make a living if you can get it. So we can imagine what Johnny Galecki, co-star of The Big Bang Theory, must be feeling having been on the hit series Rosanne for many years and now getting word that his current hit show will be renewed for three more seasons.

CBS made the announcement today and this renewal means the show will be on the network through the 2013-14 season. This doesn’t come as that much of a surprise considering how well the show does in the ratings. In addition, the network has a lot riding on the show considering it recently made a $2 Million per episode syndication deal. So, they really need it to last and obviously are willing to make the commitment to help it do just that.

Obviously, we’re thrilled here at the site because we really enjoy the show and the antics of the cast. Looking forward to watching this one for at least three more years.
